I'm able to open all my AndroidStudio projects but one. The window don't even show up and the preview form Windows is just a blank page.
I already try to clean cache, delete gradle files - from the project and the one located on the user directory - .

I was resolving this issue for weeks and this is what finaly helped:
open "File/Open Recent/Manage Projects..."
find the faulty project and remove it from recent projects
open "File/Open..." and open the project again manually
when the dialog appeared, I pressed "this window" and it finally opened.
There may be some corrupted project configuration file.
Try to create a new project, check that everything works, and then copy the app/src folder from the old one to the new one (only the src folder).
You didn't mention it but I hope you have already tried restarting your pc, otherwise try.
Can't find the option in Android Studio to switch between workspaces like in Eclipse.
Is there only way to add path when creating Project? Or any other way?
you can open a separate window that how it goes in android studio since this is based on IntelliJ IDE,
click on
File-->open-->open and select the project, this will ask you in a window saying do you want to open in new window or same click on new window.
Before start exploring Android Studio please read Project and File Structure
You can try with -> Press Cntrl+Shift+F Then change Directory Location .
Change default save location of projects (or Workspace ) in Android Studio
Just follow this steps given below, because the Android Studio doesn’t work quite like Eclipse does. It's simpler: if you create a project at, say /home/USER/Projects/AndroidStudio/MyApplication from there on all new projects will default to /home/USER/Projects/AndroidStudio. So, your current directory will be your current workspace.
1- Open new project
2- Change project location name by typing and not browse button
3- Next button will appear now
And if you want to change current then rename current directory and reopen that project.
I have been studying Android on Eclipse Mars for some time and i have been facing a constant problem everyday-the changes made in a folder/file are not recognized by some other folder/file. For example, if i create a new layout in the layout folder and then use it in the setContentView, it shows me an error ("layout-name cannot be resolved or is not a field). It works if i save the project,close it, and open it again, but this takes up a lot of time if i have more than one error, so the question-is there a way to save and refresh the project (without having to close it) so that the newly made files and folders are recognized by the java files?
Thank you.
You can refresh your project in Eclipse by right clicking on the project root folder in your Project Explorer and selecting "Refresh".
You may also want to consider checking if you have "auto build project" turned on. In your top toolbar go to Project -> Build Automatically.
If build automatically is turned off you will have to manually build your project, by Right Clicking on the project in your Project Explorer and selecting "Build Project".
However, I do agree with Pankaj Nimgade that Android Studio is likely a better entry point IDE for Android development.
Real advice: Switch to Android Studio as soon as you can. There you would sometimes have another problem called "sync" though. But it's a much better IDE and you are at least in line with Google.
on Eclipse, F5 should do the trick. Or right click your project and Refresh. Or Clean all projects. If you are still stuck, simply close Eclipse and run it again.
I can't click the run button. Does anyone know how to fix it?
Click Run on the menu and then Edit Configurations... then click on Android Application on the left and click the + button. Choose Android Application from the pop-up menu. Then pick the module (its normally app or something like that). Then click apply and ok.
If you have more errors after that, try to re-import the project in Android Studio.
When creating the Run Configuration, the dropdown for Module had only <no module> for me. Invoking menu File -> Sync Project with Gradle Files added app to the dropdown for Module. Then the Run button became enabled.
The above answer didn't work for me, instead closing the project and restaring the AS IDE worked for me.
Just click the dropdown button on left side of RUN button (in your image the dropdown which is in red box) select 'app' option from that and RUN button will be enabled.
Please refer below screenshot.
just to go File -> Sync Project with Gradle files then it solves problem.
for flutter project, if the run button is disabled then you have to
tools>> flutter>> flutter packages get >>enter your flutter sdk path >>finish
This should solve your problem...
Above answer didn't work for me, just do click File -> Invalidate/cache -> Invalidate and Restart.
open your existing application by selecting build.gradle file. it will automatically sync the project and run button will be clickable
Run 'app' button disable issue coming sometimes in Android Studio Dolphin
Sync your project with gradle files
It was quite silly for me, I just opened the Run > Run Configurations window
everything seemed to be fine there, I didn't change anything, when I closed the window the button was enabled.
If you have changed jdk version then go to File->Project Structure->Select SDK Location from left bar->update JDK Location in editbar in right bar.
If your IDE is in power save mode, then the run button etc. are also disabled.
You can verify this via the file -> power save mode, make sure it is disabled.
If you are on a Mac, try clicking on File, then click on "Sync project with Gradle files" .... Run button should turn green again in a few seconds.
if you're importing an eclipse project to android studio, you'll also encounter the same issue as above. Double Check if grade>app has
apply plugin: 'com.android.application' on the top as sometimes android studio imports it as a library.
You have to reconfigure the FlutterSDK path in Android Studio: Go to Setting -> Language & Frameworks -> Flutter and set the path to Flutter SDK
I just clicked on the debug icon and it started working.
Build->Clean Project
make the run button enable again in my case
For me increasing the version of compile SDK to latest solved my issue, Go to
build.gradle(app-level)
compileSdkVersion 30
Because My Emulator is Api-level 30
Select the project view in the android studio.
Remove all gradle folders.
Restart the android studio.
This will work.
The issue is happening since the gradle was configured for an android studio in another machine and the files pushed on the git and are using in your studio.
After removing these gradle files and restarting the studio, the studio will generate gradle files for your system. This will solve the issue.
I opened the wrong folder.... Verify is your root folder in Android studio has the build.gradle file.
If you are trying to run the Flutter Project in Android Studio, and the run button is disabled then here is the solution
Click on add configuration
and select Flutter and then select the main class in dataentrypoint
I'm using Linux where I had a symlink in my home folder pointing to a folder containing the Android Studio projects. Loading a project using the symlink failed, loading a project from the folder where the symlink is pointing to worked!
My solution was to go to that multiselect button, then "Edit Configurations" -> Go to "+" and select the module (in this case it would be an app if you do not have a multiproject -> then apply and OK
Happened to me twice, and then I figured out it happened after I upgraded my flutter version. When I opened (flutter SDK path) in (flutter) tab in (system preferences) I found it empty.
Solution was to point out to flutter directory on my disk from (flutter SDK path) in (flutter) tab in (Android studio preferences).
Run button is bounded with Configuration that is why you should check if your project is build, synced and indexed and after that you can select a Configuration
For me, more than 1 instance of adb was initialized and due to this run button was disabled. I had to open ActivityManager (on mac) and kill all the initialized adb instances.
go to Build-> Clean Project
Selecting a different build variant (in the Build Variants view), then reselecting the initial build variant, fixed this issue for me.
Here is what I have done: Downloaded and installed android SDK, eclipse and added the google repo for developer tools.
Issue is, when I got to Projects->Properties it is greyed out.
I don't understand why? Here is an image for reference:

I need to go into properties to make android SDK is installed properly.
Thank you.
Your Package explorer is empty. First create a new project File->New->Android Application Project. Then you can check Projects->Properties.
Or path to your android workspace is not proper.Select File->Switch Workspace to switch to proper workspace.
Do right click on your project folder and click on the properties.Then you will able to find the property dialog box.
And after that the project ->property will be enable.
